Filed: 1974-04-25
Abstract: 1471785 Elastomer coated metal mesh path: spray coating EXPANDED METAL CO Ltd 15 April 1975 [25 April 1974] 18180/75 Headings B2E and B2L A metal mesh path 8, e.g. of steel or galvanised steel, which is capable of receiving a spray or projection rendering of material such as plaster or mortar is provided on its rear surface alone with a coating of an adhesive stuck directly to the metal mesh and forms a continuous or discontinuous elastic membrane 33 over the apertures 9 of the mesh. Suitable elastomers include natural rubber. butyl rubber, nitrile rubber and neoprene and they may be applied by spraying from solution. Metal mesh sheets are conveyed by carbon belt conveyors 14, 15 through spraying chamber 12 and drying chamber 13. Control box 18 is connected to containers 20 of neoprene solution and pipes 22 lead to distribution box 23. Solution is conveyed to spray heads 27, which are suspended from carriage 26 by pane 28, by flexible hoses 24. Neoprene may be recirculated from box 18 to the spray heads and back, solution discharged from the spray heads being made up by suction from one of containers 20. Carriage 26 can reciprocate across chamber 12 driven by endless chain 30 from electric motor 32 so as to spray the whole surface of sheet 8. Heated neoprene solution forms a coherent but discontinuous coating on strands 10 and across apertures 9. The coated sheet passes on to conveyor 15 and thence through drying chamber 18 where radiant heaters 35 drive off solvent. Entry and exit ends of chambers 12, 13 are closed by curtains 36 and solvent vapour is extracted by fans 37 and ducts 38.

The dyes colour nitrogenous fibres in red and blue shades.  In an example 1-amino-3 : 6-bis(diethyl-sulphamyl)-8-naphthol is dissolved in glacial acetic acid and diazotized and the diazo solution is added to an aqueous solution of N-phenyl-1-naphthylamine-8-sulphonic acid containing polyglycerol ricinoleate to give 3 : 6-bis(diethylsulphamyl) - 8-hydroxy- 41-phenylamino-51-sulpho-1 : 1-azonaphthalene.

Title: ª‡-cyanomethyl-ª‡-methyladipates and preparation thereof
IPC: C08K5/16
Filed: 1957-06-13
Abstract: Compounds suitable as plasticizers, e.g. for polyvinyl chloride, are of formula:,  <FORM:0855883/IV(a)/1> where R is an esterifying radical of 1-14 carbon atoms.  Specified types of R radical are alkyl, alkenyl, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl, aralkyl and alkoxyalkyl radicals.  By hydrolysing and heating, such compounds are converted to an anhydrido-acid, which by reaction with isocyanates yields foams.  The compounds or the anhydrido-acid may be converted to triesters, e.g. the tri (2-ethylhexyl) ester, which are plasticizers for polyvinyl chloride.  On catalytic reduction, the compounds yield esters of 3-(3-carboxybutyl)-2-pyrrolidinone, which are plasticizers for polyvinyl chloride and polyacrylonitrile-containing plastics.ALSO:The invention comprises compounds of formula:  <FORM:0855883/IV(b)/1> where R is a monovalent esterifying group of 1-14 carbon atoms, each R being the same or different, and their preparation by reacting HCN with a compound: <FORM:0855883/IV(b)/2> at a temperature of about 150-340 DEG C. in the presence of an alkaline catalyst which generates cyanide ion from HCN.  When R is methyl or ethyl, other R radicals may be introduced by trans-esterification.  Specified types of R radicals are alkyl, alkenyl, cycloalkyl, alkylcycloalkyl, cycloalkyl-alkyl, aralkyl and alkoxyalkyl radicals.  Suitable alkaline catalysts include alkali metals and their carbonates, and lower alkoxides, oxides, cyanides and peroxides of alkali and alkaline earth metals, tertiary amines and quaternary ammonium bases.  The HCN may be used in the gaseous or liquid state.  The compounds of the invention are useful as plastizers, synthetic lubricants and fungicides and insecticides. They may be hydrolysed and heated to form an anhydrido-acid; this or the compounds themselves may be converted to triesters, e.g. the tri(2-ethylhexyl) ester. Catalytic hydrogenation of the compounds of the invention gives esters of 3-(3-carboxybutyl)-2-pyrrolidinone.ALSO:Foams are stated to be formed when isocyanates are reacted with the anhydrido-acid obtained from HOOC. <FORM:0855883/V/1>ALSO:Compounds of fungicidal and insecticidal activity, employed e.g. in standard 10% dust formulations, have the formula:  <FORM:0855883/VI/1> where R is an esterifying radical of 1-14 carbon atoms.  Specified types of R radicals are alkyl, alkenyl, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl, aralkyl and alkoxyalkyl radicals.

Abstract: 777,783. Jointing. AMERICAN IRON & MACHINE WORKS CO., Inc. June 28, 1955 [July 1, 1954], No. 18691/55. Class 83 (4). [Also in Groups XXIV and XXVIII] One end of a drill pipe has a collar 10 formed thereon which is connected to a tool joint 11 embodying a pin 12 for making a tapered screw connection to the socket of another tool joint 61 for example; the tool joint 11 may be formed with a socket instead of the pin 12. A socket at the collar end of the tool joint 11 comprises a conical portion 20, a cylindrical threaded part 21 leading to a smaller diameter cylindrical portion 22 extending to the inner socket shoulder 23. The inner end of the collar 10 incorporates a cylindrical neck 31, a cylindrical threaded part 32 and a conical portion 33 having an undercut 34. The tool joint socket, which is shrunk on to the collar 10, has a mouth 50 of reduced wall thickness so that the stresses produced by the shrink fit place the material of the inner surface 51 of the mouth 50 close to the elastic limit whereupon in use the added bending stress causes the surface 51 to be taken beyond the elastic limit so permanently enlarging the mouth 50 and allowing a more gradual bending of the drill collar and a lowering of the stress concentration at this point with a transfer of some of the stress to the undercut 34, which latter is prestressed by cold rolling or working. The wall thickness of the pin 12 is less than that of the corresponding part of the collar 10. In a modification two pieces of drill pipe may be coupled directly without the use of a tool joint. In another modification, the tool joint has a socket at each end into each of which is inserted the collar of one of the drill pipes to be joined.

In a self-exciting synchronous dynamoelectric generator having a single stator core 7 carrying an A.C. output winding 4 and an exciter A.C. winding 8 and cooperating with a rotor Er carrying a main field winding 2 supplied through a rectifier 14 from the exciter A.C. winding 8, an auxiliary field D.C. winding 5 or 11 produces the exciter A.C. winding output by a reluctance change effect in the exciter flux path. In Fig. 2, the stationary D.C. winding 5 coaxial with the generator produces a homopolar flux 6 but alternatively may be mounted on the rotor, whilst in Figs. 3 and 4, not shown, such winding (10) and (11) is mounted in the A.C. output winding slots of the stator and produces a heteropolar flux the slot pitch being a multiple of twice the main winding pitch. In Fig. 6, the rectifier 14, comprising semiconductor elements, is controlled by a regulator 17 responsive to units 15, 16 which respectively set the desired and represent the actual voltage output. A similar regulator 18 controls the D.C. supply from the A.C. winding 8 to the winding 11. Instead of having salient poles 1 the rotor may be non-uniformly slotted.

The wheel 3 is driven by the meter through gearing 6, 7, 9 and a price-change wheel 10 carried by a detachable, spindle 11 mounted at one end in a spring-bracket 14. The wheel 2 is driven from the coin-action through a star-wheel 16 which is moved one tooth at each rotation of the disc 17. To reduce resistance of the meter drive, n spring 18 is placed in tension by the setting- mechanism and urges the wheel 3 in the direction in which the meter drives it. For setting to zero and opening the switch, the shaft of the wheels 7, 9 is carried by a pivoted bracket 26 which is urged towards the wheel 10 by a spring 30 so far as allowed by an adjusting nut 28 on a rod 27 pivotally connected with the bracket. When the glaring 7, 9 is disengaged, the spring 18 returns the disc 1 to the zero position. A slot 20 in the disc 1 co-operates with a lever to control the switch as described in Specification 316.740, [Class 38 (v), Electric switches &c.], and a projection 1<c> on the disc actuates a lever to hold the coin-receptacle out of register with the coin slot when the maximum number of coins is inserted, as described in Speonication 319,085.
